May 13, 1929. ,Serial No.362,629;

This invention relates to that class of appliances generally referred toin the art as automotive accessories, and it has more particularreference to a characteristic form of vacuum cleaner such as isespecially'useful for cleansing the upholstery andinterior of thetonneau of an automobile or the like.

In carrying the invention into actual practice I have found it expedientand practicable to utilize an electric motor driven fan which iscooperable with a suction hose and a refuse and dirt conducting pipev ina maner someignated by the reference character 4. This may be of anyappropriate construction. It is what similar to an ordinary householdvacuum cleaner.

Thespecific details and their particular association andarrangement willbecome morev readily apparent from the following description anddrawings.

In the drawings -'Figure 1 is a top plan view of the complete structuralarrangement made in accordance with'the present invention and showingthe details in section and elevation; Figure 2 is a transverse verticalsection taken approximately uponthe plane of the line 2-2 of Figure 1.

I Figure 3 is an end elevational view of the suction hose casing.

Referring now to the drawings and especially to Figure Iit will beobserved that the electric motorand its casing is generally desprovidedwith a housing 5 of general cylindrical form accommodating the suction.and exhaust fan 6. Connected to the lower end portion of 'thishousing asseen in Figures 2 and 3 is an exhaust connection 7 with which a flexiblepipe or tube 8 is connected. This is provided at its discharge end witha bracket 9 which is adapted to beattached to the floor or other portionofthe car to discharge the dirt and refuse. This peripheral arrangementof exhaust is similar to that in an ordi nary vacuum cleaner.'. Thehousing here is provided with a central outstandingneck 10 with which ametallic nipple 11 is swivelly connected as at 12. This nipple is inturn connected to the intake end of a flexible suction hose 13. Inaccordance with the present invention this hose ,is confined in anapdespropriately constructed a casing generally ignated by the referencecharacter 14;. This casing is provided at ;its'opposite-'end; withbearings, one of which is provided with a bushing formed with a simplebearing hole; Thiscase ingis formed with a removableend plate or head 16to permit access to the interior thereof, and is alsoprovidedwith'suitable attaching brackets '17. whereby it may beconnected to theinstrument boardor other part of the automobile in' ajconeealedposition.

spring wound drum 18 of general cylindrical 'Mounted for rotation inthis casing isia form havingiits peripheral portion fprovid'ed* fl fwith corrugations. .At one end the drumis' provided witha hollowbearingsleeve-19 rotatable in the bushing 15... The opposite end isprovided. with aflan'ged bearing spindle 20 mounted for rotationinthe-bearinghole in the head16; The reference character: 21

designates a return spring suitably, anchored and cooperatingto wind thehose onto the.

peripheral corrugated portion of the drum 18. The caslng as seen lnF1gure 2 is provided with a hose outlet 22 and the intake end of thesuction hose is provided withan appropriate nozzle 23.

The fan is confined in an appropriately con- 'structed housing wherebyto produce suction through the hose and to discharge the dirt throughthe flexible'pipe and to a suitable point of deposit. The hose'is woundon a spring returned drum in acoiled fashion.

Therefore, whenever the operator desires to clean-the interior of thebody of the car it i is necessary only to grasp the nozzle 23 and topull it outwardly away from the casing 14. This unwinds the hose fromthespring wound drum. 7 The nozzle is utilized in the customary manner andthe suction produced by the fan draws in the dirt particles through thehose f 5 where they are dis- 7 into the fan housing v charged throughthe pipe 8. It is believed that the reader in consider:

drawings will be able to obtain a clear 1uningthe description inconjunction with the derstanding of the construction and arrange- I mentof parts as well'as'the features and, ads i0 vantages of the invention.Therefore, a more lengthy description is regarded unnecessary.

Minor changes in shape, size, and rearrangement of details coming withinthe field of invention claimed may be resorted to in actual practice ifdesired.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is 1. In a Vacuum cleaner, a drum having aperipheral opening, a reel within said drum having spindles rotatably'connected to the drum, a flexible hose trained about said reel movablethrough the opening and having a portion thereof extended centrallythrough the reel, a rigid nipple extending through one of said spindlesand connected to the centrally disposed portion of said hose, andsuction creating means having a casing rotatably receiving said nipple,said casing and the nipple being formed with an interfitting annulartongue and groove connection permitting rotation of the nipple withrespect to the casing. V

2. In a vacuum cleaner, a relatively fixed drum, a reel arranged withinthe drum and having spindles rotatably connected to the drum, a flexiblehose trained about said reel and having one end portion arranged axiallyinternally of the reel, a nipple engaged with said one end portion ofthe hose, said nipple extending through one of said spindles, the

other end portion of said hose being movable through an opening providedtherefor in the periphery of said drum, and a suction device operativelyconnected with said nipple exteriorly of said drum. y

In testimony whereof I aifix my signature. HOLLIS B. HALL.
